In the equation ax2 + bx + c = 0, where a, b and c are constants and a ≠ 0, what is the value of b?

(1) 3 and 4 are roots of the equation.

(2) The product of the roots of the equation is 12.

I believe the question is ax^2 + bx + c = 0

IMO A

from 1, when we know that the roots of the equation are 4 and 3, this means their product will be 12

and we can 12 in 1 way, when b = 7, since both roots are +ive

from 2, now when we know that value of roots is 12,

we can get the product in 2 ways when b=7 or b=-7

making this statement insufficient.
